Bc it known that I, FRANK BLooMrNG- DALE, a citizen of theUnited States` of America, and a resident of Voorheesville, Albany county, New York, have invented certain new and useful Improvements in Dumping- I/Vagons, of which the following isa specification.

My invention relates to dumping-wagons; and the object of my invention is to provide an attachment for a rearend dumping wagon whereby the box after dumping may be automatically replaced in a horizontal position, together with such elements and combinations as are hereinafter more particularly set forth. I accomplish this object by means of the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a section along the lines X X on Fig. 2. Fig. 2 is a plan. side elevation of the mechanism for moving the box backward and forward in a horizontal plane. Fig. 4 is a plan of the frictionroller, showing the clutch.

Similar characters refer to similar parts throughout the several views.

The box A is mounted on the frame B, which frame carries the axles C and D, upon which the wagon-wheels W,W, W', and W are placed. To the bottom of the box A, about midway between the ends, I secure the projection E, carrying the spindle F, upon which is mounted the rollers G G, respectively, which rollers engage the frame at g g, thus permitting a movement of the box in a horizontal plane upon the frame. The forward end of the box has a projection H, adapted to extend beneath the plate J when the box is in a horizontal position, which will tend to prevent a teetering of the box until the projection H is withdrawn from contact with the plate J. On the plate J, attached to the frame at the forward portion thereof, I place a ratchet M and dog m, engaging therewith a spindle N to carry the said ratchet, and also a pinion n. The spindle N preferably is bent or has formed thereon a handle O. Meshing with the pinion n is a gear P, upon the hub of which is arranged a pinion p, which engages the rack R. The rack R, arranged on the plate R is connected, by means of the arm r to the spindle F, which carries the rollers G and is attached by means of the projection E to the bottom of the box A, as aforesaid. This is so arranged and connectedfup that the operation of the Fig. 3 is a detail spindle O will move the rack either backward or forward, as desired, and therefore will move the box A either to or from the' front of the wagon. When the box A has been moved so that the center will pass the support of the frame, itwill dump, the end of the box falling to the ground.

For the purpose of drawing the box onto the frame from the dumped position I have invented the following device: Mounted on the shaft 5 are the friction-rollers 6 6, adapted to en age the peripheries of the wheels W W, the s aft 5 being suitably mounted in the frame B. Shaft 5 has attached thereto in any suitable manner a chain or rope 7, which is secured to and wound upon the reel 8 on said shaft 5. On suitable ears on the side or bottom of the box A, I mount the sheaves 9 and 10, said sheaves 9 and 10 being separated from each other, said sheave 10 being preferably near the front of the box, and over which sheaves said rope or chain 7 passes. On the forward portion of the frame I secure a sheave 11, said chain or rope 7 passing over said sheave and fastened to the bottom of the box A at 12. y Thus when the wheels W W are moved forward, the friction rollers 6 6 will revolve and wind up the chain or rope 7, which will draw the forward end of the box A downward until it rests upon the horizontal portion of the frame and is drawn on the frame until the projection H engages the plate J, when the box will be held securely in position.

In order to move the friction-rollers 6 6 in contact with the wheels W W and when desired to separate the said friction-rollers from said wheels, I have arranged the pedal-lever 13, which is in the form of a bell-crank lever fulcrumed at 14 and attached to the rod 15, which is secured to the lever 16, the end of said lever 16 being secured to the arm 17, attached to the shaft 5, carrying'the frictionroller, said lever 16 being fulcrumed between its connection with the rod 15 and arm 17. Thus when the foot is placed on the pedal-lever 13 the friction-roller 6 will be brought to engage the wheels W W. The friction-rollers 6 6 are preferably provided with a clutch 21, keyed to the shaft 5 and provided with a dog 22, engaging suitable projections 23 on the under side of the run of the rollers 6 6. The dog may be provided with a supportingarm 24 to hold it in place to engage the projection 23. This clutch is arranged to provide for the moving of one wheel in the oppo- ICO IOS

IIO

site direction from the other or 'for one wheel remaining stationary when the other is in motion'during the replacing of the dumped box in position on the frame.

What I claim as my invention; and desire to secure by Letters Patent is- 1. In a dumping-wagon, the combination -with a wagon of a pair of frictionerollers mounted adjacent to the rear wheels of said wagon; a shaft carrying said 'friction-rollers; a series of sheaves attached to the frame of said wagon and to the box; a cable passing over said sheaves attached to said box at one end and to the shaft carrying said frictionrollers at the other end; a means for causing said friction-rollers to engage said wheels; a rack; a gear and pinion engaging said rack; a lever and dog Vfor operating said gear and pin ioon; a connection between said rack and said ox. A

2. In a dumping-wagon; the combination with a wagon ofa dumping-box connected therewith; a'racl; a gear and pinion engaging said rack; a lever and dog for operating said gear and pinion; a connection between said rack and said box so connectedup'that by the operation of said lever said wagon may be moved forward or backward on its frame, substantially as described.

3. In a dumping-wagon, a movable box; a means Vfor causing said box to move; a pair of friction-rollers; a clutch connected with the shaft upon which said friction-rollers are mounted; :a means for causing said frictionrollers to be engaged'by said clutch when the rollers are moved in one direction and to be disengaged when moved in the opposite direction; a means for setting said friction-rollers in contact with the wheels of said wagon and removing the same from contact there-f.

with, substantially as described.

4. In a dumping-wagon; a movable box; a means for causing said box to move; a pair of frictionerollers; a shaft upon which said friction-rollers are mounted; a clutch conh nected with said shaft; a means for causing said friction-rollers to be engaged by said clutch when the rollers are moved in one direction and to be disengaged when moved in an opposite direction; a means for setting said friction-rollers in contact with the wheels of' said wagon; and removing the same from contact therewith; with a rack; a .gear and pinion engaging said rack; a lever and dog for operating said gear and pinion a connection between said rack and said box, substantially as described.

5. In a dumping-wagon, the combination with a wagon of a pair of friction-'rollers mounted adjacent to the rear wheels of said wagon; a shaft carrying said friction-rollers; a series of sheaves attached to the frame of said wagon and to the box; a cable passing over said sheaves attached to said box at one end and to the shaft carrying said frictionrollers at the other end; a means for causing said friction-rollers to engage said wheels; a clutch connected with saidshaft, a meansfor causing said friction-rollers to be engaged vby said clutch when the rollers are moved in one direction and to be disengagedl when moved in the opposite direction.
